For a species that is distributed between an aqueous sample and an organic extraction phase, the quantity extracted by the organic phase is O A. less efficient at a higher temperature if the solubility of the species in both layers remains unchanged O B. larger if the total volume of the organic phase is used in portions rather than all at once O C. less if ten extractions are mad than if five extractions are made O D. maximal if the species is weakly acidic and an alkaline aqueous phase is used O E. dependent only on the total volume of the organic phase used

Volumetric Analysis The mass of KHC8H4O4 is measured to the nearest milligram; however, the volume of water in which it is dissolved is never of concern—water is even added to the wall of the Erlenmeyer flask during the titration. Explain why water added to the KHC8H4O4 has no effect on the data, whereas water added to the NaOH solution, may drastically affect the data.
